Patent DE-4036370-A1 (DE)
Title: Stand-shaped material winding system
Inventor: HUBRICHT GERHARD DIPL PHYS DR
IPC: B65H55/04
Filed: 1990-11-15
Abstract: In order to effect monitoring and control of orthocyclically wound coils the surface of the coil (11) is illuminated with light (18), in the zones in which the layers of the winding bend to one side. The reflected light (19) is detected and the reflection bands which the reflection creates from the zones are checked to ascertain whether they are parallel. If a change occurs in the distance between the reflection bands, the control unit (21) emits a corresponding signal to the winding machine (14) or to the motor (16) in order to effect a correction to the winding process.

Title: Surveillance of surrounds in real-time to detect hostile incoming weapons
Inventor: COHEN JEAN-PIERRE DAVID
IPC: G06T7/00
Filed: 1990-12-01
Abstract: The surveillance system has infra-red detectors (11) delivering a cyclic scan of the space round the ship. The signals are analysed by extraction of pixels distinct from the background. The extraction process (2) delivers information on the selected pixel and on the surrounding pixels to the processing unit (3). The processing unit looks at the surrounding pixels to check whether they might represent a hostile weapon.  The extraction unit includes an image memory to allow it to produce secondary image data for the processor. A graphic processor takes data from the image memory. The processing produces a point function and a recalculated contrast factor.

Patent DE-4109996-A1 (DE)
IPC: F26B23/00
Filed: 1991-03-27
Abstract: The invention relates to a method and apparatus for surface treatment of objects made of metals such as iron and nonferrous metals and/or plastics, composite materials and the like in a pretreatment plant for subsequent painting and/or powder coating in an appropriate plant having a water pretreatment plant connected downstream. In order to enable the disposal of waste water to be avoided altogether or reduced to a very small quantity of waste water in this, the invention proposes that a waste water treatment plant is connected downstream of the plant, in which treatment plant industrial evaporation processes are carried out, the energy for which originates from a process which is directly or indirectly connected to the painting and/or powder coating plant. This "waste energy" originates, for example, from warm air which is released by the painting or powder coating plant.

Title: Pallet conveyor with horizontal flat belt - has parallel fixed guide track with rollers at sides of pallet resting on fixed track
Inventor: SCHINDEHUETTE MANFRED
IPC: B65G17/00
Filed: 1991-06-20

USE/ADVANTAGE - The pallets can be easily moved and stopped without undue high force required.
Patent DE-4121276-A1 (DE)
Inventor: HAAKE GERHARD DR ING
IPC: C01F7/786
Filed: 1991-06-27
Abstract: Described is a method of preparing sulphate-containing basic poly(aluminium chloride) solutions. This is done by disintegrating aluminium-containing salts with hydrochloric acid, filtering off the solid precipitate from the resultant suspension and evaporating down the residue-free solution to crystallize out AlCl3 x 6 H2O. The AlCl3 x 6 H2O obtained is then decomposed by heating at 150 to 200  DEG C to give a solid basic aluminium chloride which is placed in aqueous sulphuric acid and dissolved to form Al(OH)xCly(SO4)z. Finally, the basic aluminium chloride sulphate solution obtained is warmed for 1 to 3 hours at 40 to 70  DEG C.

Patent DE-4134471-A1 (DE)
Inventor: VOLZ PETER DR
IPC: B60T8/34
Filed: 1991-10-18
Abstract: Described is a flow-control valve for an anti-blocking hydraulic brake system, the valve comprising a choke of constant cross-section (metering orifice 35) and a choke of variable cross-section (differential pressure controller 23, 37). The cross-section of the differential pressure controller is determined by the pressure drop across the metering orifice (35). The metering orifice takes the form of an interface between a channel (33) of small cross-section and a channel (34) of larger cross-section. At the interface between the two channels, the change in cross-section is preferably step-like. When fluid flows through the channels (33, 34), turbulence occurs in the interface zone (35), this turbulence reducing the effective cross-section of the laminar-flow region, thus producing a throttle action.

Title: Car headlamp - has optic fibre bringing light to shaped emitter so that triangular beam passes through prism and lens
Inventor: ERNST HANS-OTTO DR
IPC: F21V5/00
Filed: 1991-11-29
Abstract: A headlamp for a car has a light source sending light down an optic link to an emitter with a lens between this and the outer surface. To create an asymmetric dipped light, there is a "light disc" between emitter and lens which scatters the light beam, eg, by vertical flutes. This disk is prismatic in shape and can deflect the beam to any required height if adjusted in position within the headlamp unit. The emitter is the shape of a long box, the light emerging from an end face. The top and sides of the box are flat, the bottom has a ridge so that the emerging beam has a triangular cross-section. ADVANTAGE - Simple and inexpensive design giving both main beam and dipped beam functions.
